The problem was tracked to use of the grpcomm.onesided_barrier to control daemon/mpirun termination. This relied on messaging -and- required that the program counter jump from the errmgr back to grpcomm. On rare occasions, this jump did not occur, causing mpirun to hang.
This patch looks more invasive than it is - most of the affected files simply had one or two lines removed. The essence of the change is:
* pulled the job_complete and quit routines out of orterun and orted_main and put them in a common place
* modified the errmgr to directly call the new routines when termination is detected
* removed the grpcomm.onesided_barrier and its associated RML tag
* add a new "num_routes" API to the routed framework that reports back the number of dependent routes. When route_lost is called, the daemon's list of "children" is checked and adjusted if that route went to a "leaf" in the routing tree
* use connection termination between daemons to track rollup of the daemon tree. Daemons and HNP now terminate once num_routes returns zero
Also picked up in this commit is the addition of a new bool flag to the app_context struct, and increasing the job_control field from 8 to 16 bits. Both trivial.

This required modification of the errmgr.update_state API so the pid could be passed in to the function that could update the proper data record(s). All calls to that API have been updated as well, but I obviously couldn't test them all.
Thanks to Dong Ahn (LLNL) for catching this problem!
Also fixed debugger daemon cospawn, both for initial launch and attach-while-running modes. Tested and verified on rsh and slurm.

* add hnp and orted modules to the errmgr framework. The HNP module contains much of the code that was in the errmgr base since that code could only be executed by the HNP anyway.
* update the odls to report process states directly into the active errmgr module, thus removing the need to send messages looped back into the odls cmd processor. Let the active errmgr module decide what to do at various states.
* remove the code to track application state progress from the plm_base_launch_support.c code. Update the plm modules to call the errmgr directly when a launch fails.
* update the plm_base_receive.c code to call the errmgr with state updates from remote daemons
* update the routed modules to reflect that process state is updated in the errmgr
* ensure that the orted's open the errmgr and select their appropriate module
* add new pretty-print utilities to print process and job state. Move the pretty-print of time info to a globally-accessible place
* define a global orte_comm function to send messages from orted's to the HNP so that others can overlay the standard RML methods, if desired.
* update the orterun help output to reflect that the "term w/o sync" error message can result from three, not two, scenarios

Continue the reorganization of the configure system. Move files from the main config directory to their appropriate level-specific config directories. Modify the configure system to correctly handle compiler detection, test, and setup so that all things pertaining to opal and orte are done at the lower level, with the ompi configure system only looking at mpi-specific options.
Ensure the wrapper compilers for orte and ompi only get built when appropriate. Add support for c++ to the orte wrapper compilers, both script and non-script versions.
This commit was SVN r22138.
Add a new tm ess module that exploits this capability.
Update the various plm modules to enable it - just a minor change reflecting an added param to a plm base function.
Additional fixes included:
1. remove an erroneous cleanup of session directories in the tool finalize procedure - tools don't create session directories to begin with!
2. fix a duplicate free when attempting to execute a non-existent app
3. cleanup an typo in the comm utilities
4. fix comm_spawn - was perturbed by the changes in pack/unpack of orte_job_t to properly support orte-ps
Been tested on slurm and tm machines, using all tests in orte/test/mpi. May run into issue with command line length on large jobs due to inclusion of node info to support static ports - will fix this next with addition of regexp generator to compress that info.
This commit was SVN r21248.
This causes the orteds in the routing tree to remain alive until all termination "acks" from orteds below them have passed through. Thus, if we use static ports, we no longer require a direct orted-to-mpirun connection.
Also modify the binomial routed module so it conforms to what all the other routed modules do and have all messages pass along the routing tree instead of short-circuiting between orteds. This further reduces the number of ports being opened on backend nodes.

- Delete unnecessary header files using
contrib/check_unnecessary_headers.sh after applying
patches, that include headers, being "lost" due to
inclusion in one of the now deleted headers...
In total 817 files are touched.
In ompi/mpi/c/ header files are moved up into the actual c-file,
where necessary (these are the only additional #include),
otherwise it is only deletions of #include (apart from the above
additions required due to notifier...)
- To get different MCAs (OpenIB, TM, ALPS), an earlier version was
successfully compiled (yesterday) on:
Linux locally using intel-11, gcc-4.3.2 and gcc-SVN + warnings enabled
Smoky cluster (x86-64 running Linux) using PGI-8.0.2 + warnings enabled
Lens cluster (x86-64 running Linux) using Pathscale-3.2 + warnings enabled
This commit was SVN r21096.
Only proc_info.h-internal include file is opal/dss/dss_types.h
- In one case (orte/util/hnp_contact.c) had to add proc_info.h again.
- Local compilation (Linux/x86_64) w/ -Wimplicit-function-declaration
works fine, no errors.
Again, let's have MTT the last word.
This commit was SVN r20631.
Often, orte/util/show_help.h is included, although no functionality
is required -- instead, most often opal_output.h, or
orte/mca/rml/rml_types.h
Please see orte_show_help_replacement.sh commited next.
- Local compilation (Linux/x86_64) w/ -Wimplicit-function-declaration
actually showed two *missing* #include "orte/util/show_help.h"
in orte/mca/odls/base/odls_base_default_fns.c and
in orte/tools/orte-top/orte-top.c
Manually added these.
Let's have MTT the last word.
This commit was SVN r20557.
1. remove direct routed module (hooray!)
2. add radix tree routed module (binomial remains default)
3. remove duplicate data storage - orteds were storing nidmap and pidmap data in odls, everyone else in ess
4. add ess APIs to update nidmap, add new pidmap - used only by orteds for MPI-2 support
5. modify code to eliminate multiple calls to orte_routed.update_route that recreated info already in ess pidmap. Add ess API to lookup that info instead. Modify routed modules to utilize that capability
6. setup new ability to shutdown orteds without sending back an "ack" message to mpirun - not utilized yet, will require some changes to plm terminate_orteds functions in managed environments (coming soon)
Initial tests indicating that fully routing comm via defined routing trees may not actually have a significant cost for operations like IB QP setup. More tests required to confirm.
This will require an autogen...
This commit was SVN r19866.
This needs some soak time to ensure we haven't opened any race conditions. I tried to loop everything in the shutdown procedure through that trigger event call to ensure it all goes through the one-time locks as it did before so that someone hitting ctrl-c when we are already shutting down shouldn't cause problems. Just want to let people use it for awhile to verify.

* add "register" function to mca_base_component_t
* converted coll:basic and paffinity:linux and paffinity:solaris to
use this function
* we'll convert the rest over time (I'll file a ticket once all
this is committed)
* add 32 bytes of "reserved" space to the end of mca_base_component_t
and mca_base_component_data_2_0_0_t to make future upgrades
[slightly] easier
* new mca_base_component_t size: 196 bytes
* new mca_base_component_data_2_0_0_t size: 36 bytes
* MCA base version bumped to v2.0
* '''We now refuse to load components that are not MCA v2.0.x'''
* all MCA frameworks versions bumped to v2.0
* be a little more explicit about version numbers in the MCA base
* add big comment in mca.h about versioning philosophy
